1. Plot Overview
1.1 The Summoning
The protagonist, Takuma Sakamoto, is a reclusive gamer who spends most of his time playing the MMORPG Cross Reverie. Known as one of the most powerful players, he controls the character Diablo, a Demon Lord feared by many. However, Takuma’s life takes a dramatic turn when he is mysteriously transported to another world, one that closely resembles the game he dominates. Upon arrival, he discovers that he has been summoned by two girls—Rem Galleu, a Pantherian, and Shera L. Greenwood, an Elf. The summoning ritual was intended to enslave Diablo, but due to a reflection spell, the girls themselves become bound to him.
1.2 Adjusting to a New World
Takuma, now Diablo, must navigate this new world where his in-game powers are real. Despite his overwhelming strength, Takuma struggles with severe social anxiety, leading him to adopt the arrogant and confident persona of Diablo to interact with others. The series follows his journey as he aids Rem and Shera in their personal quests, encounters various enemies, and ultimately seeks to find a way back home—if he even wants to leave.
2. Main Characters
2.1 Diablo (Takuma Sakamoto)
Takuma Sakamoto, now Diablo, is the protagonist who embodies the archetype of an overpowered character in an unfamiliar world. While he is confident and unbeatable in battle, his true personality is shy and introverted. The dichotomy between his in-game persona and real-life personality creates a unique dynamic that drives much of the series’ humor and character development.

2.2 Rem Galleu
Rem is a Pantherian girl with a serious and composed demeanor. She initially summons Diablo to help her with a personal quest—seeking to rid herself of the soul of the Demon Lord Krebskulm, which is sealed within her body.

Alicia is a human knight with a strong sense of justice. She is introduced as an ally to Diablo and his companions, though her true intentions and inner conflicts add layers to her character.
